摘要:This paper discueses the finite element method of calculating deformation at convex-arc with single-point mesh of model gi gear with double-circulararc tooth profile and presents that the factors effecting the deformation is module,helix angle and coefficient of elasticity. Based on numerical analysis,the equations of calculating the deformation by regression are given. This is usful to analysis of the deformation and vibration of the gears.

摘要:Based on the experimental measurement of a 2-stage gear reducer on torsional vibration characteristic, the dynamic parameters are identified and a new method which uses a simplified three-mass-spring model to substitute complex gear reducer is proposed, and the simplified model characteristic parameters are identified. The effective method used in the dynamic analysis of gear transmission system has been obtained.

摘要:In this paper,the principle of toroidal drive and the forming process of the stator for this kind of drive system are analyzed. By enveloping method of gear meshing theory,the tooth profile equation of the stator is introduced. on the basis discussed above,the enveloping method of manfactruing the stator is studied and the equipment to accomplish the enveloping method is designed and manufactured. Finally,the stator of toroidal drive is manufactured on the hobbing machine by enveloping method.
摘要:In this paper, The equations of the tooth profile curve of variable-speed ball drive are derived based on the engagement theory. The closed and successive conditions of the tooth profile curve are analysed. it provides theoretical basis for further research.
摘要:In the light of the addition of two screws, the distribution of instantaneous axes along the common perpendicular of the two screws is determined and all possible sorts of axodes are derived kinematically with the pitch of the relative motion screw in the gear pair as the basis and the transmission ratio i as an independent variable.
摘要:Based on the analysis of two kinds of the controlled boiler variator, the kinematics and the dynamics of the selected variator are discussed in this paper. The formulations of it’s efficiency and torgue are given.
摘要:Planetary traction drive composed of cylindrical rollers has the feature of extreme low noise and vibration. In this paper,the principle of the planetaryrroller traction drive is studied and the design of the mechanism for producing a compressive force to be exerted between all the rollers and the ring has been done. As an application of the transmission, the main points of design of a planetary-roller traction reducer for the use of coolling tower are given.
